Unit 4: DNA & Protein Synthesis

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA, resulting in two DNA molecules, each containing one original strand and one newly synthesized strand.

Front

What is the base pairing rule in DNA?

Back

In a molecule of double-stranded DNA, the amount of Adenine (A) is always equal to the amount of Thymine (T), and the amount of Guanine (G) is always equal to the amount of Cytosine (C).

Front

When does DNA replication occur in the cell cycle?

Back

DNA replication occurs during the S phase of interphase.

Front

What type of molecule are DNA and RNA?

Back

DNA and RNA are classified as nucleic acids.

Front

Where is DNA primarily located in a eukaryotic cell?

Back

DNA is primarily found in the nucleus of eukaryotic cells.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand during DNA replication.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains the sugar deoxyribose, while RNA is single-stranded and contains the sugar ribose.

Front

What is transcription in protein synthesis?

Back

Transcription is the process by which the information in a gene is copied into messenger RNA (mRNA) from the DNA template.

Front

What is translation in protein synthesis?

Back

Translation is the process by which ribosomes synthesize proteins by reading the sequence of mRNA and assembling the corresponding amino acids.
